Changes of the wax contents in mixtures of olive oils as determined by gas chromatography with a flame ionization detector.
J. AOAC Int. 95(6) , 1720-4, (2012) Mixing of refined olive-pomace oil with virgin olive oil is a fraud that has been tried often. Normally, the tests that detected the fraud were determinations of wax esters, erythrodiol+uvaol, and stigmastadienes contents. The most common is the determination... |

Study of skin anti-ageing and anti-inflammatory effects of dihydroquercetin, natural triterpenoids, and their synthetic derivatives.
Bioorg. Khim. 38(3) , 374-81, (2012) Accessible triterpenoids of ursane and lupane series, the flavonoid dihydroquercetin and their synthetic derivatives with polar substituentss were tested in vitro for inhibition of collagenase 1 (MMP-1) in UVB irradiation assay. Ursolic acid and uvaol disucci... |

[Synthesis and antitumor activity of betulin, erythrodiol and uvaol aminopropoxy derivatives].
Bioorg. Khim. 37(3) , 414-24, (2011) The synthesis of aminopropoxy derivatives of betulin, erythrodiol, uvaol and oleantriol via cyanoethylation of triterpenoids hydroxyl groups and subsequent reduction of cyanoethyl fragments is described. High and specific in vitro antitumor activity (cytotoxi... |
